Course objectives

Assist students to be aware of and to understand:

  • Four basic physiological principles, and be able to illustrate these with examples, and relate new material to these principles.
  • The distinction between evolutionary responses (adaptation) and within-individual responses.
  • The importance of modern evolutionary approaches to the study of environmental physiology.
  • Mechanisms available for response to environmental challenges (including different responses at different time scales).
  • General mechanisms frequently involved in a variety of responses
  • The variety of environmental challenges influences affecting all organisms at all times, and how different types of challenge may interact.
  • Some incredible examples of physiological responses to environmental challenges.

 

Course outline

  • Basic concepts and general principles
  • Evolutionary processes
  • Oxygen
  • Temperature
  • Water and ions
  • Deep sea

 

Mark distribution

  • Final exam: 40%
  • 2 x Midterm exams: 25% each
  • Tutorial presentation: 10%

 

Course schedule

* Powerpoint files will almost always be available before the lecture.

** Readings (both texts are on reserve in library):

 

W & al = Willmer, P., Stone, G., & Johnston, I. 2005. Environmental Physiology of Animals.  Second Edition. Blackwell. ISBN 1405107243.

 

M & S = Moyes, CD & Schulte, PM 2006.  Principles of animal physiology. Pearson Benjamin Cummings.  ISBN 0805353518. 

 

Check to make sure that you have the correct edition – the reading material should match up with the material on the powerpoints!

 

*** M & S, Ch. 10 provides a great overview of various topics covered in ‘Oxygen’ section.

 

**** The material covered in the temperature section is largely drawn from Willmer et al’s Chapters 8, 11.3, 12.3, 13.3, 15.3 and 16.  I have rearranged the material substantially, so there is not a simple correspondence between a lecture and a chapter in the text.
